Lay-instructed driver training is an important ingredient of the Swedish driver licensing system since it contributes to increased safety among novice drivers after they have obtained a licence. This study shows that apart from these benefits in terms of safety effects, there are problems regarding the way in which lay-instructed training is carried out and the accidents that occur during practice. A cost benefit analysis showed that the advantages are greater than the disadvantages. An important conclusion from the study is that measures need to be introduced in order to reduce the number of accidents that occur during pracitice, and that there is still a large potential for increasing the effects of lay instructed training on the accident situation after obtaining a licence. This can be achieved through improved structuring and planning of where, when and how training are carried out. Mandatory education of lay supervisors and improved co-operation between supervisors and driving schools is suggested. For the covering abstract see ITRD E124157.
